IMPROVED MACHINE FOR MAKING RAKE-TEETH.

Specification forming part of Letters Patent No. 15,] 95, dated June 24,1856.

To all whom it may concern:

Be it known that I, CHARLES R. SoULE, of

' Fairfield, in the county of Franklin and State of Vermont, haveinvented a new and Improved Machine for Making or Forming WVire Teethfor Horse-Rakes; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specification, in which Figure 1is a side View of my improvement. Fig. 2 is a plan or top view of thesame.

Similar letters of reference indicate corresponding parts in the twofigures.

Myinvention consists in a peculiar arrangement of parts for bending orforming the coil in the wire.

A represents a rectangular frame, in the upper part of which ahorizontal bed or platform Bis placed, and O is a shaft, which is placedin the upper part of the frame A, the shaft being placed transverselyover the bed or platform and having a pulley D placed loosely upon it atone end. To the opposite end of the shaft there is attached a projectiona, the outer end of which is hooked or curved, so as to form a step orgroove 6 on its outer side, as shown clearly in Fig. 2.

E represents a frame formed of two uprights 0 0, connected by across-bar d. The lower end of this frame works upon a rod 6, the ends ofwhich are fitted in cleats or projectionsff on the base of the frame A.One of the uprights c has a plate g attached to its upper end, saidplate being grooved on its upper edge. A plate h, having a step i on itsouter side, is attached to the upper end of the other upright c.

F represents a lever pivoted at to the bed or platform B. One end ofthis lever is connected by a rod is to one of the uprights c of theframe E, and a rod Z is attached to the opposite end of the lever F,said rod being fitted in guides on the bed or platform and projecting ashort distance beyond the edge of the bed or platform.

To the end of the shaft 0 and adjoining the pulley D there is attachedan arm G, said arm having a right-angled lever H pivoted to it. Theshorter arm 79?. of the lever H has a catch a at its outer end, and aspring 0, which is attached to the outer end of the arm G,

bears against the outer end of the arm m of the lever H. On the innerside of the pulley D there is a pin 10.

I represents a treadle or lever, which is attached to the frame A, saidtreadle having a pin g on its outer side. The outer end of the lever Iis connected by a rod rwith an arm 3, which is pivoted to the upperendof the frame A. An upright spring t is attached to the end of the arm 3.

The operation is as follows: The Wires of which the teeth are formed arecut of the proper length, and are placed one at a time upon the groovedplate 9 and step 11, the end of the wire bearing against a step j, (seeFig. 1,) the wire being shown in blue. The treadle or lever I is thendepressed by the attendant or operator and the pulley D is rotated bymeans of a belt in the direction indicated by the arrow, and the pin 10on the side of the pulley D will strike against the catch at, and thearm G and shaft 0 will be rotated with the pulley D. As the shaft 0rotates, the pro jection a at the end of said shaft will bend the wireand cause it to coil around the end of the shaft, and the upper part ofthe frame E will be gradually moved out from the frame A in consequenceof the wire being wound around the shaft. As the upper part of the frameE moves outward, the rod Z will be shoved outward considerably beyondthe platform or bed B in consequence of the rod 70 acting upon the endof the lever F, and when these turns or coils of the wire have beenformed on the shaft 0 the rod Z will be sufficiently beyond the edge ofthe bed or platform for the longer arm a of the lever H to catch againstit. The pin 19 on the pulley D will consequently slip past the catch iton the shorter arm m of the lever and the pulley will rotate, while theshaft 0 will remain stationary. When this takes place, the elasticity ofthe rake-tooth or the wire, caused by the coil or winding of the wireupon the shaft 0, will throw up the arm G, and the longer arm a of thelever H will catch upon the upper end of the spring t. The wire orrake-tooth is then removed from the shaft (1, another wire is fitted inthe machine, and the operation'repeated.

The above machine is extremely simple, works rapidly, and is notexpensive to manufacture.

having the lever I-I secured to its end, the above parts being arrangedand operating as shown, for the purpose specified.
